Trivia: Harvey Dent, who would later become Two Face, was originally going to be in this film instead of Max Schreck. The plan was to have Catwoman turn him into Two Face the same way she ended up killing Schreck, except of course Dent obviously would've survived and become Two Face.

Trivia: Sean Young very much wanted the role of The Catwoman. During pre-production she arrived at the studio in a Catwoman costume to confront the makers of the movie. She used other people scouting the studio grounds, using walkie-talkies to communicate, to track down the producers.

Trivia: The massive Gotham City sets were all constructed so that could be mobile, and they were often shifted between days of filming. Michelle Pfeiffer said in an interview that she routinely got lost on her way to filming each day, because she couldn't find the correct set.

Trivia: Robin was originally supposed to be in this film, but was cut at the last minute. His story was that Penguin killed his family during the circus, and wanted revenge, but too many elements of revenge already existed in the film and it would have been overwhelming.

Trivia: Neither Tim Burton nor Michael Keaton had been signed up in advance for a sequel. Burton came on board only after the script met all his demands, whilst Keaton only agreed to do the second film after a serious hike in salary.
